There are a number of things that can affect the resolution of a bright-field microscope. One of the most important factors is the resolution of the microscope’s optics. Poor optics can cause the microscope to have poor resolution, which can make it difficult to see the objects in the image. Additionally, the magnification of the microscope can also play a role in the resolution of an image. A microscope with a high magnification will be able to see more details in an image than one with a lower magnification. Finally, the air pressure inside the microscope can also affect the resolution of an image. When the air pressure is high, the light waves will be scattered more and the image will be less clear.
